The National Rifle Association, among the nation's largest and most influential lobbying groups, said "the Second Amendment isn't up for debate." "The NRA supports the Second Amendment rights of all law-abiding Americans to purchase, possess and use firearms," the group said in a statement Friday. "NRA does not, and will not, support any policy proposals that implement sweeping gun bans that arbitrarily strip law-abiding citizens of their Second Amendment rights without due process," the group said. Gun Owners of America, another major gun rights lobbying group, said it "opposes any and all gun bans. Full stop."
